Postfix: Connect; Immediate Disconnect
I'm trying to get a PHP mailing script (using PEAR) working on my web server connecting to my remote Postfix box, and each time the script executes, I get no errors in either my PHP output or my Postfix logs, but no email is sent.
The corresponding log items for the request are this:
Nov 19 10:15:34 mailer postfix/smtpd[2611]: connect from xxx-xxx-xxx-xxx.static.cloud-ips.com[xxx.xxx.xxx.xxx]
Nov 19 10:15:34 mailer postfix/smtpd[2611]: disconnect from xxx-xxx-xxx-xxx.static.cloud-ips.com[xxx.xxx.xxx.xxx]
I know my Postfix server is working correctly, since I have other applications that can send mail to it just fine (and they're relayed correctly).
I also know that this script is working since I can copy it verbatim (except for changing the location of the PEAR libraries) to another web server (on HostGator) and it connects and sends the email fine.
I wish I could get some sort of error message to give me some kinda clue as to where to go from here, but I've got no error messages: just a connection followed by an immediate disconnection. I am only having this problem trying to send mail from this specific web server.
What's causing this and what can I do to fix it?
The Web Server I'm having issues with is running Ubuntu 8.04.2 LTS (hardy).
